Using the Scientific Calculator

This advanced calculator is designed to handle complex mathematical expressions by correctly following the order of operations (PEMDAS/BODMAS). This ensures that your results are always accurate, no matter how complex the equation.

Order of Operations (PEMDAS)

PEMDAS dictates the sequence in which operations are performed to ensure a consistent, correct result:

  1. Parentheses
  2. Exponents (and roots)
  3. Multiplication and Division (from left to right)
  4. Addition and Subtraction (from left to right)

For example, the expression 5 + 2 × 3 is correctly evaluated as 5 + 6 = 11.

Advanced Features

  • Trigonometric Functions: For functions like sine (sin), cosine (cos), and tangent (tan), you must select whether you are working in Radians (Rad) or Degrees (Deg). Be sure to enclose the function's argument in parentheses, for example, sin(30).
  • Ans Button: The `Ans` button allows you to use the result of your last calculation in your new expression.
  • Implicit Multiplication: For convenience, the calculator understands implicit multiplication. You can enter expressions like 2(3+4) or 5cos(60), and they will be correctly interpreted as 2 * (3+4) and 5 * cos(60).

For simpler, sequential calculations without PEMDAS, you can use our Standard Calculator.
